Northrop Grumman says six customers have bought missions using its upgraded orbital repair robot

9:04 am

Capitalism in space:A Northrop Grumman official has revealed that it already has six customers willing to buy missions using its upgraded orbital repair robot to fix orbiting satellites that are presently defunct due to lack of fuel.

Unlike the company’s first robotic repair satellites, dubbed Mission Extension Vehicles (MEV), the Mission Robotic Vehicle (MRV) for these new contracts will not dock directly to the satellite, but use a robot arm to attach an extension pod to each.

The primary commercial mission of the MRV is to install small propulsion devices known as mission extension pods. One of these units is inserted in the back of a client satellite propulsion system, adding six years of life to most geostationary satellites, he said.

The six customers have signed term sheets for seven mission extension pods, Anderson said. Once contracts are firmed up the company will be able to disclose their names.

The first MRV launch in 2024 will carry three pods. “With these six customers, the MRV manifest is currently filled through mid-2026,” he said. The MRV is expected to have a 10-year service life.

This MRV system is far more cost effective than the MEV, since the latter can only repair one satellite, while the former can fix several with a single launch.

Both Northrop Grumman and Astroscale (see my previous post) are demonstrating the emergence of a new cottage satellite industry, the repair of old satellites and the removal of space junk, all for profit.

Rocket Lab wins contract to launch space junk removal satellite

8:49 am

Capitalism in space: Rocket Lab announced this week that it has won a launch contract from the Japanese-based company Astroscale to launch its first attempt to rendezvous with a piece of space junk — an abandoned upper stage from a Japanese launch — in order to grab and de-orbit it.

Rocket Lab announced Sept. 21 that it won a contract from Astroscale for the launch of its Active Debris Removal by Astroscale-Japan (ADRAS-J) spacecraft. A Rocket Lab Electron will launch ADRAS-J from its Launch Complex 1 in New Zealand in 2023.

ADRAS-J will rendezvous with and inspect an upper stage left in orbit by a Japanese launch. The Japanese space agency JAXA awarded Tokyo-based Astroscale a contract in 2020 for the mission as part of its two-phase Commercial Removal of Debris Demonstration project.

The first phase of this demonstration project involved Astroscale’s current test satellite, which is presently testing capture techniques of space junk using magnets.

It appears Rocket Lab got the contract because it can place this smallsat in the precise orbit it needs, and can do it for far less than any other launch company in operation at present.

InSight detects the three more large quakes on Mars, the most powerful measured so far

8:40 am

In the past month InSight’s seismometer has detected the three most powerful earthquakes so far measured on Mars, with one located in a region where no quakes had as yet been seen.

InSight spotted 4.2- and 4.1-magnitude temblors on Aug. 25, then picked up another roughly 4.2-magnitude quake on Sept. 18 that lasted for nearly 90 minutes, NASA officials announced on Wednesday (Sept. 22).

The previous record holder, which InSight measured in 2019, clocked in at magnitude 3.7 — about five times less powerful than a 4.2-magnitude quake.

At this time scientists have only been able to roughly pinpoint the location of the two August quakes, with the 4.1 quake occurring about 575 miles away, putting it in the volcanic plains where InSight sits and closer than the location of most of the previous large quakes near the long surface fissures dubbed Cerberus Fossae 1,000 miles away.

The August 4.2 quake’s is even more interesting, as its location is the farthest away of any so far detected, at an estimated distance of 5,280 miles away. The scientists presently suspect but have not yet confirmed that it may be located in the western end of Valles Marineris, Mars’ largest canyon.

The lander itself continues to fight a loss of power due to the amount of dust on its solar panels, forcing the science team to shut down practically all its other instruments so that the seismometer could continue operating.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

A clue to the Martian history of volcanic eruptions

1:00 pm

Dark layers in Medusae Fossae Formation
Click for full image.

Anyone who has taken even a single glance at a map of Mars cannot help but recognize that the red planet was once engulfed with repeated gigantic volcanic eruptions able to build numerous volcanoes larger than anything seen anywhere else in the solar system.

The cool image to the right, rotated, cropped, and enlarged to post here, provides a clue into those past eruptions, now thought to have been active for more than several billion years, with the most recent large activity ending several tens of millions of years ago. The photo was taken on May 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows just one tiny portion of the vast Medusae Fossae Formation, the largest thick volcanic ash deposit on Mars, about the size of India and what scientists think is the source of most of the planet’s dust.

What makes this picture interesting are the dark layers in the lower hollows. They indicate that this deposit was placed down in multiple eruptions, some of which produced material that appears dark blue in MRO images, and suggest that eruption was different than previous and subsequent eruptions.

The white cross on the overview map below notes the location of this picture in the Medusae Fossae Formation.

Today’s blacklisted Americans: Republicans blacklisted 53 to 1 over Democrats on social media

12:05 pm

Silenced by Twitter, Facebook, YouTube, and Google
Republicans: Routinely silenced by Twitter, Facebook, and YouTube.

Blacklists are back and the Democrats have got ’em: According to a review of the actions of the big social media companies against politicians, the Media Research Center has found that Republicans are censored at a rate 53 times more than Democrats on social media.

The attacks on Facebook, Twitter, YouTube, Google, Instagram, and others have been against both standing Republican members of Congress as well as Republican candidates running for office, with further evidence showing that Facebook very specifically has been favoring Democratic incumbents.

Nor have the top managers and owners of these social media companies been able to counter this data.

Fired flight director accuses Virgin Galactic of lying about problems on July suborbital flight

9:19 am

A former Virgin Galactic flight director, who was relieved of his duties just before the company’s July suborbital flight that carried Richard Branson and then fired shortly thereafter, has accused Virgin Galactic of misleading the public in its statements about the problems that occurred during that flight.

Virgin Galactic has claimed that the high winds forced the spacecraft away from its planned flight path.

Mark Stucky, who Virgin Galactic fired eight days after Branson’s flight, said his former employer put out an inaccurate statement about why VSS Unity flew unauthorized into Class A airspace for 1 minute 41 seconds during its descent. Class A airspace is primarily used by airlines, cargo operators and higher performance aircraft.

“The most misleading statement today was @virgingalactic’s,” Stucky tweeted. “The facts are the pilots failed to trim to achieve the proper pitch rate, the winds were well within limits, they did nothing of substance to address the trajectory error, & entered Class A airspace without authorization.”

There is no way to know if Stucky’s accusation is correct. We might be seeing a bit of personal anger on his part considering his firing. At the same time, the FAA’s statement about this issue made no mention of winds, which suggests the Virgin Galactic statement might not be true.

Regardless, Virgin Galactic’s track record in matters of safety has not been stellar. The company needs to quickly resolve these issues or they will become a lingering sore that will damage sales for future suborbital flights.

Wuhan panic continues to shut down India’s space agency

9:08 am

While most private companies and many nations, such as China and Russia, have been launching continuously since the advent of the coronavirus panic last year, India’s space agency ISRO continues to be shut down, completing few launches with a story today suggesting that the three remaining planned launches for 2021 will likely be delayed until next year.

There have only been two launches this year – the purely commercial PSLV C-51 launch in February carrying Brazil’s earth observation satellite Amazonia-1 and the GSLV-F10 mission in August carrying an Indian earth observation satellite EOS-03 that failed.

To be sure, the space agency has plans for three more missions before the end of the year, including the first development flight of the SSLV [Small Satellite Launch Vehicle]. The other two will use India’s workhorse PSLV to launch two earth observation satellites EOS-04 and EOS-06.

“The three planned missions appear unlikely this year,” a senior scientist at the agency said on condition of anonymity.

Worse, before the year began ISRO had reduced its targeted number of missions for ’21 from 16 to 5.

The article makes believe the epidemic has shut down other programs, such as Artemis, in the same way, but that is false. NASA’s Artemis program might have lost a few months in ’20 due to the agency’s panic over COVID, but since then it has been moving as fast as it can, considering the cumbersome nature of its engineering. Even Rocket Lab, which has been badly hampered by New Zealand draconian Wuhan rules, has managed to launch eleven times since January 2020, compared to the four launches attempted by India during that same time.

Whatever has caused the shut down at ISRO, it really hasn’t been the epidemic. Something about the agency’s management and its bureaucratic culture has prevented them from resuming flights. And as they remained stalled, the private commercial companies in the U.S. and China are grabbing their customers.

Today’s blacklisted American: Weatherman fired after 33 years for not getting COVID vaccine

12:03 pm

Weatherman Karl Bohnak, now a non-person
Weatherman Karl Bohnak, now a non-person.

Persecution is now cool! Karl Bohnak, who had been a weatherman for the Michigan television station WLUC for 33 years, was fired last week because he refused to get the COVID vaccine shot as now mandated by the station.

Bohnak announced his firing in an essay on his Facebook page [requires Facebook login]. I have posted the full text at the end of this essay, also posted here, to illustrate the rational, thoughtful nature of his decision. You might disagree with him, and think he should get vaccinated, but he outlines in clear detail his valid reasons for not doing so.

His essay also raises the very valid constitutional and ethically reasons for resisting the mandate of this company.

The abrogation of our liberty and freedom under the guise of a pandemic is very disturbing to me. Hopefully, whether you lean right or left, you are concerned about what has occurred the last year-and-a-half. I just wanted to go about my business, “live and let live”, and keep my mouth shut. But this act by the federal government through corporate America has brought me to a crossroads. Our way of life, our freedom and liberty, is collapsing before our eyes.

Sadly, Bohnak is not alone in this. Thousands of people across America are willingly losing their jobs because they will not submit to this dictatorial and entirely unconstitutional vaccine mandate. As the left has loudly proclaimed for decades, these Americans are declaring, “Our bodies, our choice!”

From the beginning, the data said that the lethality of COVID would merely be a variation of the flu. » Read more

Martian mountaintop

Mountains on Mars

The outcrop top
Click for full image.

Cool image time! The photo to the right, cropped, reduced, and enhanced to post here, was taken on September 21, 2021 by Curiosity’s high resolution mast camera, and shows the top of that spectacular rock outcrop about 200 feet to the west of where the rover presently sits. The top image, from my September 16, 2021 post, “Curiosity: Into the Mountains!”, indicates the location of the photo with the black rectangle. The red dotted line indicates the rover’s future planned route.

I estimate the whole outcrop is about 100 feet high, which means the cliff section seen in the photo to the right is probably about 30 feet high. It would make a great challenge for any number of rock climbers I know.

What makes this image especially striking are the overhanging rocks at the peak’s top. In the Martian gravity, about one third that of Earth’s, it is possible for much more delicate rock shapes to remain structurally stable, and the sharp jagged boulders hanging out at the top of this cliff demonstrate that in a quite breath-taking way. On Earth such delicate rocks would likely have quickly fallen.

The Curiosity science team is obviously most interested in the massive layers revealed by this cliff. I am also sure they are also as enthralled by the scenery as I am.
